Jazper,
I'm curious to know what meds you are on for depression/anxiety...
Could there be a switch of meds in your future?
In my experience, I have found that a anti-depressant and an anti-anxiety combo works the best, but you have to give the meds time to work!
heck, I thought Australia was where all the happy people lived...you know down on the sandy beaches saying...ello matey to everyone...
